This invention relates to regulating devices for presses for producingflour paste articles.

It is known to provide presses for producing flour paste articles,particularly vermicelli, with a dispensing tube and to insert therein anumber of cylindrical sizing members. The slender strands of vermicelliare formed by pressing the material through these sizing members in theform of separate bundles of strands which bundles, as a rule, align inorder to be formed into bunches by so-called bunching machines.

The present invention is particularly concerned with regulating devicesfor presses for producing flour paste articles which devices, however,do not discharge individual bundles but individual strands of flourpaste, which are preferably in the form of macaroni or spaghetti.

According to the invention, the strands discharging from sizing membersconnected to a dispensing tube are united into groups, the velocity ofdischarging of the strands being regulatable for each group separately.

With this arrangement it is possible to deposit the strands on the barsof agrating in such manner that the bars are hung with strands uniformlythroughout the grating. The flour paste articles are then dried in aknown manner.

It is, however, necessary that the flour paste strands hanging on thebars shall be practically of a uniform length. In the usual forms ofdispensing devices the velocities at which different strands dischargeare, however, not exactly alike. Thus, when it is required to obtainstrands of uniform lengths resort must be taken to cutthe bars, wherebyundesirable waste accrues. This drawback is eliminated by the invention,in that the velocity of discharge of the individual groups of strands isre'gulatable.

Advantageously, for each group of strands a cylindrical sizing member isprovided from which the strands discharge longitudinally of a generatrixof the cylinder and which is arranged within a head connected to thedispensing tube. The heads can be detached from the dispensing tube veryquickly in simple manner by virtue of which the interchanging of sizingheads requires the operation of the press to be discontinued only for avery short time providing two sets of such heads are employed.

An embodiment of the invention is illustrated on the accompanyingdrawing by way of example only, in which Fig. 1 shows a side elevationof a dispensing ting the strands after they have been placed on device,according to the invention, partly in longitudinal section;

Fig. 2 is a bottom view of Fig. 1;

Fig. 3 is a cross section of Fig. l, and

Fig. 4 is a horizontal section on the lineIV-IV of Fig. 3.

The dispensing device shown is provided with a dispensing tube I towhich are connected a plurality of heads 2 within each of which a sizingmember 3 provided with a plurality of discharge openings is arranged.The dispensing tube I is electrically heated along its full length bymeans of subdivided heating elements 4 which are pressed onto the flatsurfaces la of the dispensing tube by plates 5, in such manner, thateven if only groups of heating elements are connected with the heatingcurrent the dispensing tube is heated uniformly throughout its length. Asheet metal shell serves as a heat insulating and guard member againstthe accidental touching of current carrying parts. Control screws 1 arescrewed in dispensing passages lb of the dispensing tube l and aresecured in position by lock nuts 8 in such manner that the streamingarea of the passage and thus the stream of paste passing therethroughcan be varied by the passage being throttled more or less. By this meansthe non-uniform feed to the individual heads 2 resulting from a drop inpressure in the dispensing tube I can be equalized, so that the velocityof discharging of the flour paste strands from the sizing members 3 canbe adjusted to a uniform value also.

The upper cylindrical neck of the head 2 is connected to the dispensingtube 1 by a screw sleeve 9 through the intermediary of a sleeve H. Thesleeve II is rotatable relative to the screw sleeve 9 when, the latteris loosened. The sleeve is, however, secured against axial displacementby an annular spring clamp l and is provided with two diametricallyopposed longitudinal grooves Ha. The cylindrical neckof the head 2 isprovided with two studs 2a corresponding to these grooves so that theneck can be detached or reinserted in position when the sleeve II hasbeen turned through 90 from its position shown in Fig. 4. On theinsertion of theneck of the head 2 in the sleeve II the latter is turnedthrough 90 again into the position shown in Fig. 4, whereupon the screwsleeve 9 is tightened and consequently the head 2 is secured to thedispensing tube I in readily detachable manner.

The cylindrical sizing member 3 which is provided with sizing aperturesfor individual paste strands along a generatrix of this member is ingcustomary practice and established knowl-- edge of the art to thepresent disclosure while the scope of the specification and claims isnot to be regarded as limited except therein.

I claim:

1. In a dough press for forming strands of dough, means forming a commonfeed channel, a plurality of hollow head members, the form of said headmembers being such that the cavities thereof taper toward said channel,means forming individual connecting passages between said channel andthe smaller ends of said cavities, cylinders having sizing openingsserving as molds for the dough strands to be formed in said hollowmembers, and individually adjustable means adapted to extend into saidpassages between said channel and said sizing openings for regulating asspecified the cross-section of said respective passages to regulate theflow of dough to said respective molds.

2. In a dough press for forming strands of dough, means forming a commonfeed channel, a plurality of hollow head members, the form of said headmembers being such that the cavities thereof taper toward said channeland the e, d opposite the channel is elongated in one dir tion, saidmembers each being provided with an elongated slot at the elongated endthereof, means forming individual connecting passages between saidchannel and the smaller ends of said cavities, cylinders having sizingopenings lying in a line and serving as molds for the dough strands tobe formed in said hollow members, and individually adjustable meansadapted to extend into said passages between said channel and saidsizing openings for regulating the cross section of said respectivepassages to regulate the fiow of dough to said respective molds.

3. In a dough press for forming strands of dough, means forming a commonfeed channel, a plurality of hollow head members, the form of said headmembers being such that the cavities thereof taper toward said channel,means forming individual connecting passages between said channel andthe smaller ends of said cavities, said connecting means beingdetachable from said channel forming means, cylinders having sizingopenings lying in a line and serving as molds for the dough strands tobe formed in said hollow members, and individually adjustable meansadapted to extend into said passages between said channel and saidsizing openings for regulating the cross section of said respectivepassages to regulate the flow of dough to said respective molds.
